Application m June 1, me. Serial Io. 114,215.

My invention relates to improvements in automatic aper sheet feeders .ordlnarily used for folding paper box gluing machines,

open end envelope machines, parafining mac i nes, and "those of similar nature, and is designed as an im rovement of the machine shown and descri ed in Letters Patent of the United States #1,033,040, issued to me Jul 16, 1912. b

'l he object of my invention is to rovide means for keeping the surface of t e feed wheel moist during the feeding operation to insure the greatest efliciency of the feed wheel and dispense with the usual practice of moistenin the surface of the feed wheel with a wet 0 0th, a manual 0 eration requiring considerable time and la or to keep the cloth pro erly saturated and cleaned.

A furt er object is to provide a moisteningdevice which can be easily and quickly ad usted transversely of the machine to position it for contact with any particular feed wheel.

A further object is to provide a moistening device having means for manual operation for starting the flow of the moistemrfg fluid with provision for operatingilthe moisteniizlg device mechanically at t e desired spee y A further'object is to provide means for kee ing the surface of the feed wheel clear of int or other forei material which has a tendenc to accumu ate on the rubber surface of ti: efiiciency.

A further object is to provide a feed wheel moistening and cleaning device of simple inexpensive construction, and at the same time, strong and durable.

Other ob ects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming a part of this specification, Figure 1 is a plan view of an automatic paper sheet feeder to which my invention as been applied;

Figure 2 is a vertical section on the line 1--1 of Figure 1, looking in the direction of the arrow; 1

Figure 3 is an enlarged view of a portion of Figure 2;

Figure 4 is a plan view of the lint brush e wheel and destroy its feeding.

,a similar manner to the shaft is turned in the same directionby hand; v

' Figure 8 isa detail section of the gearreducing mechanism;

Figure 9 is a detail section through the gears and water pot device which serves to transfer the water from the water pot to the brush.

In the drawings, 2 represents the frame of an automatic feeder correspondin to that used in the conventional type of fo ding paper box gluing machine, provided with the usual lower feed drum 3, the carrier belts 4 driven in the usual manner and a feed wheel 5 mounted on a shaft 6 driven through frictional contact of the wheel 5 with the belt 4, preferably of rubber. 7 represents a feed table or hopper. A shaft 6 has bearings in brackets 8 and 9 provided on each side of the'machine frame. Above the shaft 6, is a shaft 10 also havin bearings in the brackets -8 and 9. This sha t 10 has the function of tying the brackets 8 and 9'together and is secured in the brackets by suitable setscrews 11 and 12. Belowthe shaft 10, I provide a shaft 13 having its end rtion secured in rackets 8 and 9. I also provide anotherfshaft 14 having bearings 15 and 16 in the brackets 8 and 9 and adapted to revolve freely therein. For driving the shaft 14, I provide aflange 17 having a hub 18 secured on theshaft 6. A stud 19 is mounted in the flange 17 and carries a pinion 20 that is adapted to mesh with spur gears 21 and 22, (see Figure 5). The gear 21 is held in the bracket 8 against rotation and its hub forms a bearing for the shaft 6. The gear 22 is, free to revolve and has a sprocket 23 thereon. The gears 21 and 22 are of the same diameter but the gear 21 has one more teeth than the ear 22 (see Figure 8). It follows, there ore, that as the flange 17 revolves in the direction of the arrow, (see Figure 8), it will carry the pinion 20 around with it, causing the pinion to roll over the teeth in the gears 21 and 22 and keeping the teeth in line at the point of contact. As the number of teeth in the gears is different, it follows that with the engagen'ient'of the driving pinion with both gears, and as one of the gears is fixed, the other or the gear 22 must advance to compensate for the difference in the number of teeth. I thus provide a speed-reducing mechanism for the sprocket wheel 23 from the rather high speed of the shaft 6 without the necessity of providing a complicated expensive speed-reducing mechanism.

To counterbalance the weight of the stud in the pinion 20, I prefer to provide a plug 24 in the flange 17 on the other side of the shaft 6. Mounted on the shaft 14 above the speed-reducing mechanism just described, I provide a sprocket wheel 25 secured by suit able means to a hub 26. In this huh, I provide a recess 27 having a roller 28 and spring 29 forming the conventional roller clutch device for driving the shaft 14 when the sprocket is revolved in the direction of the arrow, but releasing the shaft 14 when the operator wishes to turn it by hand in the same direction for the purpose of adjustment to allow access to the adjusting screws of the brushes and transfer gears as will be hereinafter described. The roller 28 operates to clamp the hub 26 against the huh 30 that is secured to the shaft 14 by suitable means such as a setscrew 31. The sprocket wheel 25 is driven through a sprocket chain 32 connecting the wheel 25 with the sprocket 23. The sprocket 23 is somewhat smaller than the sprocket wheel 25 and, therefore, serves to effect a further reduction in speed. The hub 30 is rovided with a gear 33 adapted to mesh wit 1 a ear 34 on the shaft 35. The gears 33 and 34 are of substantially the same diameter so that the speed of the'shaft 35 is practically the 821-1118 as that of the shaft 14.

The shaft 35 has bearings 36 and 37 in the arms 38 and 39 which are clamped in position concentric with the bearing of the shaft 14 by suitable clamps 40 and 41 formed on the brackets -8 and 9 and provided with cap screws 42 and 43. The purpose of this mechanism is to provide for an adjustment of, the shaft '35 with respect to the feed wheels as will appear from the following description.

Upon the shaft l4, I provide a gear 44 adapted to .mesh with a gear 45 that is mounted to revolve in a. fluid receptacle 46 on a stud 47 having a threaded portion 48 that is screwed into the side wall of the fluidreceptacle 46. A setscrew 49 adjustably secures the gear 44 to the shaft 14. The fluid receptacle 46 is held in place on the shaft 13 cap screw 50.

On the shaft 35 opposite and adjacent the gear 44 and in contact therewith, 1s a brush y suitable means such as a justed laterally aerow the machine at any point wherever it is desirable to locate the feed wheel 5. As shown in Figure 3, the

brush 51 will travel inthe direction of the arrow and contact with the rubber surface of the feed wheel 5 but will operate at a much slower speed and will, therefore, drag on the surface of the wheel and wipe off lint, dust, or any other foreign material which may accumulate on the surface of the wheel. As the brush revolves, it will also come in contact with the gear 44 and as this gear is in mesh with the gear 45 revolving 1n the fluid chamber 46, (see Figure 3), it follows that the teeth of the gear'46 will carry up such fluid as water, glycerine, or other liquid that may be contained in the fluid chamber and transfer it to the teeth of the gear 44 from whence the liquid will be icked up in suflicient quantity to keep the ristles of the brush 51 moist but not too moist or wet, to such an extent that an excess of moisture will be deposited on the surface of the wheel, but on the contrary the slightly moist bristles as they slowly revolve will deposit just enough moisture on the surface of the wheel to insure the perfect feeding efiiciency of the wheel.

The gears 45 and the brush 51 move very slowly and in changing the machine for stock of different sizes and moving the feed wheel 5, it is of course necessary to adjust the gears and the brush and to make the setscrews 49 and 53 easily accessible. I provide the clutch mechanism on the shaft 25 as heretofore described which will enable the operator to grasp and turn the shaft 14 by hand until t e screws 49 and 53 are in position to be easily reached and loosened for the desired adjustment of the mechanism.
